Latest Patents

One of Yi Zhang's latest patents is a "Magnetic sensor for superconducting quantum interference device using single operational amplifier." This invention comprises a superconducting quantum interference device (SQUID), a feedback coil, a feedback resistor, and an operational amplifier. The voltage signal from the SQUID is delivered to one input of the operational amplifier, while a bias voltage is delivered to the other input. The output of the operational amplifier connects to one end of a feedback resistor, with the other end connecting to a feedback coil that generates feedback magnetic flux. This configuration simplifies the circuit, decreases loop delay, and achieves higher bandwidth for the flux locking loop.

Another notable patent is the "Method and device for selectively detecting ferromagnetic or superparamagnetic particles." This invention relates to a method for detecting and quantifying superparamagnetic and ferromagnetic particles on analytes. The method measures a frequency component of magnetic fields generated due to the non-linearity of the magnetization characteristic curve of the particles at a mixing frequency. The device includes a container for the particles, oscillators for generating alternating magnetic fields, and a magnetic field sensor for measuring the response magnetic field.
